In my previous post I showed you how easily you can create a simple webserver using Node.js. In this post I want to show you how to make more advanced usage of node package manager.
npm initUsing node package manager you can get an even quicker start of your project by using the npm init command. So let’s get started by opening a command prompt (on windows open the Node.js command prompt). Then create a new folder and navigate into this newly created folder. In the folder execute following command and answer the questions or press enter for the defaults.

(yes) yes
After answering the questions the result should be something like above. As you can see I have changed the default name. By default node package manager uses the folder name. Play around yourself to get the desired result. You can also change the package.json after it is created.
Why do we need this package.json file?
